Question Engine Light - Oxygen Sensor

Greetings all,

I have a 2005 1500 with 176,000 miles on it. The engine light came on and I had a mechanic hook it to the computer and he said it was an O2 sensor in the exhaust system. I couldn't have him work it then. I am still driving it till I can have them work on it (This week). The question is when I come to a stop, sometimes, it just dies. I crank it and she starts right up. After a few lights, it just very quietly dies, then I crank her right back up til I get to my destination. Is this caused by the sensor or battery or alternator? Or could it be another issue. Any insight would be greatly appreciated.

Thank you,

Could be a dirty throttle body. http://www.ramforumz.com/showthread.php?t=46764

Do you specifically know which sensor ? The one before or after the Cat ?

I don't see how the sensor would be related to the stalling....... Depending on the sensor problem, I would expect the symptoms to show while driving. With that many miles I would check for vacumn leaks

Thank you for the replies. I was told it was before the Cat. But since they haven't fixed it yet, I cannot know for sure. I'll try the suggestions and let you know.

Thank you, again.

Well, thats the more critical sensor since it really determines and adjusts your A/F ratio....... but I dunno if that would affect the idle and cause it to stall vs running lean when moving........

It could be related but my gut says no

Dirty throttle bodies are common and a cheap DIY fix. Definately worth a shot before spending diagnostic and repair money at a shop.
